Metadata structure

To have better understanding metapro protocol flow 🛠️

How to read all data about Token ?

To get access to data about token You need to follow these steps:

• Enter BSC Scan
• In BNB Smart Chain Explorer find MetaproMetaAsset Contract 0xa293D68684Be29540838Dc8A0222De0c43c6b5B4

• Click on Contract and Read Contract

  

  View of contract on BSC Scan
• In this tab we have all methods which we can read from MetaproMetaAsset Contract

• Last method calls "uri" which get data about token.

  

  Method called "uri" where you can insert TokenId

• Copy link from response and paste it on new browser tab

  

  Example of JSON response with all data about token

⚠️ Hint : If you want to have parsed data like on picture above it needs JSON formatter extension installed on browser
